PBX Extension Numbers

Extensions can be in the same office or scattered all over the world and each extension can be called ‘internally’ by dialling its three digit short code or externally by adding DDIs.

It doesn’t matter where they are physically located; they always work in the same way wherever - calls between extensions are always free no matter where they are.

How do I set up extension numbers on my phones?

How do I set up extension numbers on my phones?

Each of your phones will need to be setup with the extension, rather than registering to the main account. If your account number was 30040041, then you would setup your phone to register to 30040041*200 if you wanted the phone to be extension 200. You also have to change the password for the phone; each extension has its own password. You can check the passwords for each extension here, if you're logged in as the PBX administrator.

 

If you're using hardware telephones or adaptors please check here for setup guides: but remember to login to our website using the email address and password for the extension you wish to setup. You can check the email addresses and passwords here, if you're logged in as the PBX administrator.

 

For the Xlite Softphone, either run the wizard and input the username in the above format, or, open the softphone, press F8 and put the new account number into the username and authorisatoin user boxes. Also, change the password to the one for the extension you're setting up.

 

How do I setup the PBX?

 

We’ve made it extremely easy to set up and use. It's all managed by you on our web site through one account.

 

Firstly decide how many extensions you need; don’t worry about getting it wrong - if you take too few you just add more, if you find you have too many you remove them. We don’t lock you into a contract - the most a mistake can cost you is £1! You can have any number of extensions but you need, up to 798 on one account.

 

Once you’ve decided, click on the Package Builder button below, fill in the Virtual PBX box with the number of extensions you want and press the build my package button. This takes you to the payments page. Once you’ve completed the details and pressed the ‘Make Payment’ button you’re ready to set-up the extensions.

 

Your virtual extension numbers start at 200 and each needs to be assigned a name, an email address (nb this address is where the extension holder’s Voice to Email Voicemail will be directed) and a password.

 

Once you have done this, you decide how each extension will work with incoming calls. You’ll see that an incoming call can either ring all extensions or just one. So if you want a single individual to answer the phone say, your receptionist, choose that option; otherwise choose ‘ring all’.

 

If you want individual extensions to receive incoming calls directly to their extension, you just add another incoming telephone number to your account from the Package Builder by pressing the ‘add more phone numbers’ button and mapping it to the extension.
